gorp

Etymology
The Oxford English Dictionary cites a 1913 reference to the verb. The occasionally theorised "good old raisins and peanuts" or "granola, oats, raisins, peanuts" are probably backronyms.

Noun

 * 1) A loose mixture of dried fruit, nuts, frequently salt, and sometimes other ingredients; designed as an energy supplement for use while hiking, climbing, canoeing, etc.
